A HelmetMountedSight is a new {{Defictionalization}}. It is essentially a [[{{HUD}} Heads Up Display]] that tells your [[CoolPlane fighter]]/chopper where you want the [[MoreDakka bullets]] or [[MacrossMissileMassacre missiles]] to go. It has also been upgraded to show what friendly fighters are equipped with to provide StatOVision.



* The prototype [=VF-0=] ''[[TransformingMecha Valkyrie]]'' in ''MacrossZero'' does it one better: the helmet tracks the pilot's ''eyeballs'' in order to acquire targets for the mecha's head-mounted cannons. Presumably, this became a standard feature, but this is one of only two times we actually see how it works.
** The other time it appears on screen is a blink and you'll miss it moment with Ozma in {{Macross Frontier}}.

* ComicBook/{{Deadshot}}, a Franchise/{{Batman}} villain and a member of the Comicbook/SuicideSquad and the SecretSix has one of these.

* ''Film/{{Predator}}''. The title creature's shoulder cannon moves in synch with its helmet.
** In ''AliensVsPredatorRequiem'', the Predator installs a second plasmacaster on the other shoulder, although both are controlled by the same sight.
* ''Film/BlueThunder''. The direction of the title helicopter's autocannon is controlled by its pilot's helmet.
* Nicholas Cage's character in ''FireBirds'', a rookie Apache pilot, has trouble learning to use one of these, leading to some... ''innovative'' teaching methods on the part of his instructor.
* In ''Film/HalfPastDead'', StevenSeagal's character explains to his friend (played by JaRule) how to operate a crashed helicopter's gun using the helmet. When the firefight breaks out, it comes in handy.

* ''Series/{{Airwolf}}'' has one in Stringfellow Hawke's helmet.

* There was a third-party product for the NES which was a headset-mounted zapper gun.

* A VR game like this was at Segaworld in London's Trocadero c. 1999.

* [[http://tri.army.mil/LC/cs/csa/apihadss.htm US helicopter gunships since the early 1980s have used the IHADSS system]], which can not only aim a laser designator for [[AirLaunchedWeapons the AGM114 laser-guided antitank missile]], but also aim an autocannon in the powered turret under the helicopter's "chin"
* First found on the [=MiG-29=] "Fulcrum" in the 1980's and copied by the West after discovering how effective they were from ex-[[EastGermany GDR]] examples of that plane, particularly in combination with the R-73/AA-11 heat-seeking missile.
** er, the [[http://en.wikipedia.org/wiki/Helmet_mounted_display Honeywell VTAS system]] entered service with the US Navy in the late 1970s
* The F22 and F35 are/will be equipped with these. Several attack helicopters are equipped with them as well.
** Specifically these aircraft, along with several older U.S. fighters like the F-15, F-16, and F/A-18 will be made compatible with the new Joint Helmet-Mounted Cueing System, which when combined with the new AIM-9X model of the Sidewinder allows for some absolutely gratuitous stunts involving {{Roboteching}}.
